PLEASE PLEASE PLEASE re-enforce your horizontal. I was flying on of my lasers today (the one without the re-enforcment) at 1/3 throttle in straight and level flight and I lost my horizontal and my elevators in one quick flutter of death. The wood that is included in the kit for the horizontal is of a very poor grade and will break under stress (Or no stress like mine did). When the horizontal blew off it was a wild ride for nearly 2 min. The aircraft nosed down then up then down the up then a few loops. I played with the trottle and managed to somewhat roll the airplane on its side and fly it in some what of a knife edge to the ground and I rolled out within the last few feet for an inverted landing. The only damage from the crash was a broke rudder and a scratched cowl. I have called hobbico (thats who handels the plane in the United States) and got no where with them. The guy says "hmmm...well we really havent had a problem with horizontals blowing off, call back tommarrow to talk to our R&D department". If I were you I would use some carbon fiber on the horizontal as well as kevlar flying wires. My other lasers that have the kevlar havent had a problem. I really feel that this is due to piss poor balsa included for the horizontal and the elevators (which I had replaced on the elevators).
